Why does that not need to be something like
center = .array~new(0,0,0) ?
Ah, this is new syntax sugar in ooRexx 5.0, a comma separated list of values - depending on the
location - will cause the creation of an array object containing the comma separated items.
Actually in this particular case it would have been even possible to write:
center=0,0,0 -- will create an array of these elements
Hence you can also do something like:
do n over "anthony", "berta", "caesar" -- will create an array and allow to
iterate over it
say n -- will output one name after the other
end
Or using the new "do with" ... "over" for using a supplier for the iteration:
do with index idx item obj over "anthony", "berta", "caesar"
say idx":" obj
end
will yield:
1: anthony
2: berta
3: caesar
